In Sediment Information frame, there is Sediment Info button reports the critical shear stresses and settling velocities computed based on the particle sizes entered in the Sediment Properties for the Sediment Distribution table. The critical shear stresses and settling velocities are calculated using Van Rijn’s equations (Van Rijn, et al 1984), and the resulting values are provided in the pop-up window. However, those values are calculated only to provide users a guideline for those transport parameters, and EFDC_explorer would not use the values in the pop-up window when generating the SEDZLJ model input file (bed.sdf).
